FME Form

Hi all,I have a CSV file containing stops with fields stop_lon and stop_lat. I’m trying to turn them into geometry and reproject them so I can use them with other layers.My workflow looks like this:CSV → Tester → VertexCreator → CoordinateSystemSetter → Reprojector In VertexCreator I assign X = stop_lon, Y = stop_lat. In CoordinateSystemSetter I set the source coordinate system to EPSG:4326. In Reprojector I reproject to EPSG:7856 (GDA2020 / MGA Zone 56). After running this, the points don’t land in the right place compared to my suburb polygon layer (which is already in EPSG:7856). In QGIS, both layers line up fine (on-the-fly reprojection), but in FME they don’t.Clearly I’m missing something in how I’m handling coordinate sys

Hi, I have a polygon that looks like it has some floating point issues in measures around 0. What is the best way to fix those values without affecting the legitimate values.I’m thinking extracting the measures as a list and then editing the list in python and resetting all the measures from the new list, but that seems a little convoluted.

Hello there, I really have a hard time to understand how to use the "Geometry Validator". I checked the "help" and still not sure how it works.  I checked an example in IMDF validator and not sure what is the column of "Issue to detect" does, such as "contains -0, NaN, or infinity".  I really hope someone can give me a light introduction on this transformer. Thank you and I am really appreciate your help.  

I converted the fbx model to citygml format and opened it in KITModel Viewer, but encountered an error and the model did not display。  

Hello everybody,I hope this is a the right place for a FME Realize question as this is about mobile apps (or is there a Realize subforum I missed?) otherwise please don’t hesitate to move this thread. I am just starting out with FME Realize and I noticed some weird behaviour and was wondering if this is only because of GPS position fluctuations or because of something else.I placed spheres at these two points:When I place one via rotating/moving and lock the model the other one is quite a bit offset. I doubt it is because of my data, as it is measured by a trusted surveyor.  Correctly placed sphere and line.When I

Hi! I'm new to FME and I have an issue with published parameters in a CustomTransformer.I created a CustomTransformer name "TeamsConnector" which need to use the published parameters "Message" in a pythoncaller:   Now in my main flow I use twice my custom transformer with different published parameters value. "Message 1" as a value for the first use of my transformer:    "Message 2" as a value for the second use of my transformer: 

I'm trying to create a custom transformer 'FeatureCountLogger' which logs the number of features inputted into this transformer.  The custom transformer contains a PythonCaller with the following code:   import fmeobjects class FeatureProcessor(object):    def __init__(self):        self.featureList = []    def input(self,feature):        self.featureList.append(feature)    def close(self):        logger = open(FME_MacroValues['Summarylog'], "a")        message = FME_MacroValues['Message'] + str(len(self.featureList)) + '\\n'        logger.write (message)        logger.close()      I want to use the logger multiple times, so I created a published parameter 'Message' in the custom transformer, so I can submit the text logged to each instance of the transformer.    When I'm running this I get the following error: Python Exception <KeyError>:

Hi, It seems to me that there might be an issue when I'm trying to fetch a parameter value of a Custom Transformer, from a PythonCaller inside that Custom Transformer.  If I do so, I obtain an error. When I try to do so in the main workspace, or when I add the name of the CT in the parameterfetcher, I don't get an error, and it works. See below screenshot and the attached demo workspace for an example.This seems like a bug to me, but it would be nice if the community can have a look alongside me. Kind regards, Thijs Ps. as a sidenote, I came across this Community Question in which

Hi,I’m having a issue making a TIN properly in FME. Basically FME is interpolating points/vertexes that don’t actually exist in the original data. What I want to do is make a TIN that considers only the vertexes of the features I give to it (point/lines and breaklines). I do not want FME to make up data that does not exist.Does anyone know a way that I can do this?For example in this example this is one break line. It should only have two TIN vertices (the ends). No triangles should be created from any interpolated points However, when I look at the TIN for the same spot it has created 6 vertices I am using FME workbench/form 2023. I’ve been trying diffe

Hi, I have a dynamic workspace where I am reading in multiple csv update files for multiple feature types to upsert into our database. I had set the primary key dynamically dependent on the target table in the database. I cannot set a where clause on an UPSERT (which I do use with other feature types that have the ability to do I, U, or D) so went to use the "Row Selection: Columns:" section instead. This parameter does not work in the normal way with attributes. It presumes the selected attribute is the primary key field (no orange left arrow in front of the name), rather than using the value. I tried manually adding @Value(primary_key) (the attribute that stores the primary key column name) in the parameter but the feature writer also presumes it is literal and obviously can't find a column called "@Value(primary_key)" and errors. This is something that I would like to do, and is very much a part of a dynamic workflow. Otherwise

Hi Everyone, Looking for some assistance, I’m using FME 2023.1.0.0 trying to migrate some existing Survey-123 forms and data with attachments from ArcGIS On-Line to our new Enterprise portal.Our survey-123 form has a singular photos field for tracking a picture of the bus stop, it also has a repeatable photo’s field (table) where the inspector is able to take and attach multiple deficiency photos to the stop if one exists.  In FME, I’m able to read in the AGOL feature service that hosts all of the survey information, I’m also able to write out the tabular information from the point layer to the new Enterprise feature layer that was created when I saved the Survey-123 form in Enterprise.The part that I’m currently struggling with is getting the singular photos to attach when writing the tabular information out to the Enterprise feature service so when I view the points in ArcGIS Pro, they appear in the attachments tab of the attributes editor like they currently

NullAttributeMapper, AttributeCreator or otherWhat do people use to set default values for attributes?In the case that I have is a json document - in the case values are missing I need to set a default value. Ideally I’d use an NullAttributeMapper, however, there are upwards of 10 values I need to set and I don’t want to use 10 of these. The other option I see is an AttributeCreator/Manager with conditional values which is what I would normally do.  

After adding FeatureReader_2, the reading order started prioritizing the XML block. Then, a join occurs with the Data Dictionary block, but since the XML is fully read first, when the flow reaches the FeatureJoiner, the data dictionary has not yet been processed, causing an error.This started after I added FeatureReader_2, because I need it to read shapefile files to extract the name and coordinate system, which are parameters defined in my spreadsheet with the paths to each shapefile.Is there any way to make the XML and Data Dictionary blocks read simultaneously? Or, since the FeatureReader is a reader, will it always have priority?

Hi,I am looking for a writter that will allow me to save blob data in FME Flow. On FME Form I am using AttributeFileWriter that is working completely fine 

Hello Am struggling to combine geometry of an object . I should have 19 objects there is only 1 object which just doesn’t want to combine any unknown reason…..don’t know why ? Any suggestion / idea would be much appreciated.  The reason i am combing objects is to extract the face of each object and then obtain FACE centre point for further analysis.  thank in advance 

Greets,I have two question: First one: how can I clip the green polygons based on the reds one with the same ratio?Second one: is there any way to move the red polygons to match the border of the green polygons. The Red and green polygons not in the same layer

Hi everyone!Today I’d like to share a new approach to building reports in FME, along with an entire family of custom transformers I’ve created to support it. Why I built BRGI’m a long-time fan of the HTMLReportGenerator. It lets me craft reports quickly, and I love the versatility of HTML compared with, say, PDF. I even demo it in every Intro to FME course as a great example of “let FME handle the code.”But as much as I love it, I’ve always hit three pain points:1. Plain styling – it could really use a dash of CSS/Bootstrap.2. Hard-coded content types – adding a new chart or HTML element isn’t trivial.3. Cumbersome feature ordering – managing Sorters and AttributeCreators just to control layout can get messy.Earlier this year I had to build a highly procedural report with lots of HTMLLayouters, AttributeCreators, and Sorters, and the workspace quickly tur

In the stand-alone FME Form my FME script works well. However, using the same script in ArcGIS Pro faced error saying Esri Geodatabase Writer: Feature Type Definition … was requested, but not defined. A possible reason is that you may not have permission to create the Geodatabase. The error number from ArcObjects is: '-2147467259'. The error message from ArcObjects is: {}FeatureWriter or classical Writer, there is no difference. With other FME scripts (created by others) a fgdb can be created. Why not the mine?  

Hi there,I have 2 parcel datasets, a master copy and a weekly update copy that I need to process into the master copy. Each parcel only appears once in each dataset and has a unique parcel ID so matching is fairly easy. I’ve used a change detector to flag any parcels with geometry updates, but now I need to identify the type of change that has taken place. This could involve parcels being split, merged or just the boundary being updated. What is the best way to do this? The logic in my head is this so far:Split parcels - Either, mutliple new parcels being inserted within the boundary of one that has been deleted OR Parcel boundaries shrinking and new parcels being added within boundary of originalMerged parcels - New parcel being inserted that takes the place of multiple deleted parcels OR Parcel boundaries growing to cover extent of deleted parcels

I would like to hear about everyone’s experience with “Observability” of “FME Flow” in understanding it’s health and operational usage (for example, including FME Flow in a “trace” or understanding/correlating logs in relation to metrics)My context, I’m working on maturing our GIS stack to a completely new level. Modern Observability is a major objective for us.Now, I’m working on a design and architecture where our observability platform will be able to tell us about an operation “end to end” with traces, give a high level view of failed jobs/automations/etc at a high level BUT allow us to view errors in jobs AND the system at a high level in order to know when users may be experiencing issues early on.Mainly, we want observability that will help us see wherever our users start having issues and make “incident” management a little easier for diagnostic stages.NOTE: I’m looking at the Grafana LGTM Stack as an option for us but I’d really like to hear abou

Hello,A DWG is converted to SHP with a Schema Mapper and Schema Scanner (This is a POC for a more complex workspace.).  Output FileWhat is the Q_schemam attribute that is automatically created ? (I removed it from the writer but I am curious about it). How do I remove the original attribute from my Schema Mapper ? I selected ‘Source Attribute: Remove’ in the schema mapper, but the original attribute is still outputted.  My output also contains Source Bra and Source Fea, how do I avoid writing this attributes? What are they ? Thank you

The FeatureReader for Esri ArcGIS Server Feature Service seems broken in 2024.0. I try to read the following feature type : "Zones de gestion intégrée eau par bassin versant - ZGIEBV";and I get the following error message : ArcGIS Feature Service Reader: Could not find a layer/table matching feature type 'Zones'Python Exception <FeatureTypeNotFoundException>: FMEException: 928219: ArcGIS Feature Service Reader: Could not find a layer/table matching feature type 'Zones' It seems to me like the feature type cannot contain spaces. This worked fine in FME 2023.

I'm using a FeatureReader to read an ArcGIS Server Map Service. The map service has a lot of layers (AKA: Feature Types) which I can choose from to read.If I choose a feature type name which doesn't have a space then it works but if I choose one with a space then FME Desktop errors saying it can't find the feature type with the truncated feature type name at the first space. Here is an extract from the logs below for "Fish habitat areas" as an example of it incorrectly reading "fish" as the feature type name ArcGIS Feature Service Reader: Could not find a layer/table matching feature type 'Fish'A fatal error has occurred.

Hi All,I am working on data with Line Geometry and would require some help to solve the below scenario,While plotting them on map, I see there is small gap between lines in some scenarios and would like to join them together if the distance between two lines is less.(Reason for this gap - There is an asset in between the lines which has Point geometry.- Not sure if this statement will help, JFYI)Below is an example of different line geometries joining with each other, and there are small gap in some scenariosI would like to join gap between Line 3 and Line 4.gap between Line 5 and Line 6I am not interested in joining parallel line, as they are far from each otherAny hel

I’m able to write dynamically to a file geodabase using the GEODATABASE_FILE writer with the following setupHowever, trying to do the same in a FeatureWriter fails with a cannot define schema errorSame behaviour seen in both FME 2024.1 and FME 2025.1Is this a known issue?If i try to set schema definition name to fme_feature_type_name in the Feature Writer it’s not possible, only fme feature_type is available for selectionThe only way i can seem to get the FeatureWriter writing dynamically to a File geodatabase is by adding the schema attribute to all features
